IKEA `PARASOLL` Door/window sensor #23

Open nelsonic opened 8 months ago

nelsonic commented 8 months ago

Occasionally the doors/windows of the house are left open (people forget to close them) overnight ... 😬 It hasn't been an issue yet, but the low crime rate in Braga isn't something we can rely on forever ... ⏳ So I'm considering getting door/window open sensors to test.

This is a basic reed switch with low power coms powered by AAA batteries, exactly what we need. Given the low cost - €9.99 at the time of writing - thinking of getting two to start. We have a lot of windows in this house so getting one of these for each of them might get expensive ... But for security/safety reasons, we only need to cover the bottom floor which has windows/doors that humans can enter/exit ...

I can't actually tell the specifics of what it does from the description. Does it tell you when a window has been left open for a certain amount of time?

We would ideally only want to know if windows are left open at night as I try to open the windows for an hour every day for air flow.

@iteles good question. This is a pretty “dumb” sensor. The “smart hub” is where you can apply automations. so we can set a rule to the effect of:

if (time > 19:00 AND window == open) { sendAlertToHouseMaster() }
